A fast multilevel direct solver for the Method of Moments applied to electrically small structures is presented. The approach is based on a combination of low-rank decompositions and fill-in control. It is particularly advantageous for multiple right-hand-side problems such as those encountered in digital circuit and IC analyses, as is demonstrated by numerical simulation results presented here.
